**process divergence_tensor

Description

This post-processing step computes the \(L_2\)-norm of the divergence of a given second-order tensor. Nodal values are determined by extrapolating the integration point values and averaging them for shared nodes.

Syntax

**process divergence_tensor \(~\,\) *var varname

The name of the output variable is div_varname.

Example

****post_processing
 ***global_post_processing
  **file integ
